whats a "crate" engine??

Your point is? By my (rough) calculations, you've got $8k in the engine after import tariffs and shipping, and another ~$20k in the upgrades unless you can DIY which I've never heard anyone who knows anything about turbos recommend to a newbie.

Or, for $8k you can get a HO 502 crate from GM Parts Direct. 500HP 510ft/lb direct from the crate, ready to run.

The Supra still handles alot better than an old musclecar with an axle and leaf springs in the back.

Hey cmon... you know its only about going fast in a straight line in this country... 😛

 

[halik]

the engine form japan is about 5,
the donor body is about 2 grand, the set of nice big .7/.7 turbos maybe another 3. Add it 3 more grand for the fuel system upgrades and you have a crazy fast car for under 15 grand

That is assuming you do everything yourself thought

As far as your compression ratio goes, people usually dont keep the the same as the increase the boost, most of the the time they lean it out to get the most hp

Compression ratios will stay the same no matter what psi you run 😛 It's the cylindar pressures that increase. BTW: You can hype up an RB26 all you want, no straight 6 will beat the max horsepower of a fat ol' crate V8 like a 500ci Hemi

Yeah, cause the Viper was never a huge competitor in LeMans or anything...
And the Corvette C5R was never dominant either...

I dont think the Viper has leaf springs... 😛

But the blanket statement (I know...made in sarcasm 😛) of saying "fast in US = straight" is a glaring innacuracy, just as long as you know that 😉

Yeah i know... but to the general public here... more HP sells... i doubt many of them even know the Viper and Corvette dominated their class...let alone know what the hell LeMans is... or that they even beat F550s. 😀

We aren't talking about Vpiers and Corvettes in this thread. We are talking about musclecars and Japanese I6es.

not necessarily, people who run that much psi generally lean the engines out (less fuel..bigger compression ratio) to squeeze more hp.

But yeah 426 hemi with a blower and nitrous will definitelly max out at twice the hp of rb26 with anything you can slap on it...

Sorry to resurrect this thread, but once again I have to say, fuel mixture has nothing to do with compression ratio 😉 Compression ratio is mesured by *one thing*, the amount of volume being displaced by a piston when it's down as a ratio to the volume it is compressed to, and that's it. This never changes in any engine, ever, except for some very very rare motors that have pivoting heads to vary the compression, but it's a very expensive and inconvenient idea. So for all intents and purposes, compression ratios will always be the same in any motor we have around today.

I think you have air-fuel ratio confused with compression ratio.

No.. Air-fuel ratio stays the same. He means it's virtually higher compression ratio, since it's the same as having a bigger cylinder, and that air is compressed into the same space.

 

[ndee]

no, air fuel compressino ratio is similar to the fuel engine compartment piston intake.

No, how do you define compression ratio?

Which kind? Some people are talking about static, some are talking about dynamic.

I don't know what that means. If you define compression ratio as the amount that the air is compressed, then it probably is higher with a turbo, because much more air is being compressed into a slightly bigger space.

IIRC, static compression is defined by cylinder volume. Forced induction doesn't change the volume, but the cylinder pressure.

Compression ratio has nothing to do with the amount of air compressed, it's sheerly based on volume. It has nothing to do with mass.
